摘要： A low power-consumption active matrix display device including gate lines, drain lines, and pixel electrodes, which are arranged at intersections between the gate lines and the drain lines. A drain line driver is connected to the drain lines to select a drain line and provide the selected drain line with an image signal. A gate line driver is connected to the gate lines to select a predetermined gate line and provide the selected gate line with a gate signal. Level shifters are connected to the drain line driver to operate in a time-dividing manner. Each level shifter supplies the drain line driver with a boosted voltage.

摘要： Between a positive power supply 18 and a negative power supply 19, a p-channel transistor 11 and an n-channel transistor 14 are connected in series while a p-channel transistor 12 and an n-channel transistor 15 are also connected in series. An inverted input signal *Sig1 is input to the respective gates of the transistors 11 and 14, while an input signal Sig1 is input to the respective gates of the transistors 12 and 15. As a result, of a pair of the transistors connected in series, namely either the transistors 11 and 14 or the transistors 12 and 15, when one transistor turns ON, the other transistor turns OFF. Thus, generation of through currents is prevented.

摘要： A gate line GL is set to an H level to switch on a selection TFT (10) and a short-circuiting TFT (16). A current corresponding to data (data current (negative)) is applied to a data line (Data). In this manner, a current corresponding to the data current flows through a voltage converter TFT (12) and a driver TFT (14) and light is emitted from an organic EL element (50). A gate voltage of the voltage converter TFT (12) and the driver TFT (14) in this process is stored in a storage capacitor (C). Even after the data current is switched off and the selection TFT (10) and the short-circuiting TFT (16) are switched off, the driver TFT (14) continues to apply a current. After a predetermined emission period elapses, an erase line (ESL) is driven to switch an erase TFT (18) on to discharge the storage capacitor (C) and switch the driver TFT (14) off.

摘要： A first transistor and a second transistor which serve as switches are connected with each other in series between a data line and a gate electrode of a third transistor which drives a diode. A characteristic of the first transistor is made to differ in terms of current driving capability from that of the second transistor. A storage characteristic of one of the first transistor and the second transistor is made higher than that of the other transistor whereas the current driving capability of the other transistor is raised, and so that leakage current in the first and second transistors which are connected in series is significantly reduced.

摘要： A color display device comprises a plurality of pixel regions having different areas, which may be realized by differences in the horizontal width, corresponding to different color components. Each pixel region is provided with a first thin film transistor for selectively supplying a signal corresponding to a display information to the pixel region, and a storage capacitor connected to the first thin film transistor for retaining the signal corresponding to the display information. A plan view distance obtained by projecting onto a display plane surface an extent from the capacitor-side end portion of a gate of the first thin film transistor to the storage capacitor is configured identical in the respective pixel regions. With this arrangement, the need to adjust for each color component the writing time and rate of the signal supplied via the first thin film transistor can be eliminated, even when the pixel regions have different areas.

摘要： An organic EL device is fabricated by a novel method to reduce the decrease or the dispersion of the luminance of the organic EL device caused by the voltage drop. A display apparatus comprises: optical elements; a power supply line which supplies electrical energy to each of the optical elements; and a signal line which transmits a control signal to each of the optical elements. The resistance of the power supply line is lower than the resistance of the signal line. The cross section of the power supply line may be enlarged, or the resistivity of the constitutional material of the power supply line may be lowered to lower the resistance of the power supply line.

摘要： A variation in a display image and duration of a residual image are reduced to improve quality of display of an active matrix type display device. A control circuit sequentially outputs a pre-charge pulse signal PCG1 and a storage capacitor control pulse signal SC1 in synchronization with a falling edge of a vertical start pulse signal STV. A pre-charge TFT in a pixel in a first row is turned on according to the pre-charge pulse signal PCG1. As a result, a source and a gate of a driver TFT are short-circuited, both an electric potential at the gate and an electric potential at the source of the driver TFT become a positive power supply electric potential PVdd, and the driver TFT is turned off. After that, the storage capacitor control pulse signal SC1 rises to a high level, and the electric potential at the gate of the driver transistor is raised by capacitive coupling. With this, electric characteristics of the driver TFT are initialized.
